I'm glad I'm not the only one that sees that 3% as not being a small delta, but in fact... quite a large one. I think it comes out to like 1.5" or something if I remember my math from back in the day semi-correctly.

I'll ask that you add the INVO's and the previously mentioned Bridgestones. (Dueler H/P Sport) There is also a cheaper non "RFT" version of that tire. It should probably be on the list as well.
The 315 RFT is supposedly the widest that we can get on our vehicles. It's a really fat tire. And on SOME it will rub a bolt on the inner fender in the rear end. Search... you'll find a few writeups and the solution. It's easy.

Also shouldn't forget the Yokohama ADVANSPORT tires, nor the Pirelli PZero's. Good tires. Very pricey.
And the Dunlop SP Sport Maxx & Michelin's. For those that want very very expensive tires.

I have the Bridgestone Dueler H/P Runflat tire in the 275/315 combo. I absolutely love this setup and as you have shown here there is zero difference in the front to rear circumference. I did go with the Bwoody endlinks in advance as it does give more clearance. I believe most will rub if you keep the stock endlinks.
